John Calvin Commentary Genesis 33:12

"And he said, Let us take our journey, and let us go, and I will go before thee." — Genesis 33:12 (ASV)

Let us take our journey. Although Esau was inclined to benevolence, Jacob still distrusts him. It is not that he fears being ensnared or suspects that treachery lies hidden under the guise of friendship; rather, he cautiously avoids new occasions of offense, for a proud and fierce man might easily be exasperated again by slight causes.

Now, although the holy man had just reason for fear, I still dare not deny that his anxiety was excessive. He suspected Esau's generosity; but did he not know that God stood between them, who, as he was convinced by clear and undeniable experience, watched over his salvation? For, from where did such an incredible change of mind in Esau come, unless he had been divinely transformed from a wolf into a lamb?

Let us then learn from this example to restrain our anxieties, lest, when God has provided for us, we tremble as if in a matter of doubt.
